with further reading, i believe i have a clearer picture of smpte
--"30 non-drop" runs at 30 fps, with continuous counting.
--"29.97 drop" is the same as "30 drop", running at 29.97 fps, and
using discontinuous counting such that the frame times don't slip too
much from normal timepieces over longer durations.
--"29.97 non-drop" runs at 29.97 fps, with continuous counting -
usually used in i.e. commercials which, due to their brevity do not get
to the first dropped frame-count in the "drop" format.
so, my understanding is that we have 2 out of the above 3 formats
covered in ardour's MTC options, right? if one wishes to use "29.97
non-drop", it seems not currently possible.
